Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

open access: yesMolecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

The role of disulfide bonds in a Solanum tuberosum saposin-like protein investigated using molecular dynamics.

open access: yesPLoS ONE, 2020
The Solanum tuberosum plant specific insert (StPSI) has a defensive role in potato plants, with the requirements of acidic pH and anionic lipids. The StPSI contains a set of three highly conserved disulfide bonds that bridge the protein's helical domains.

Compounds targeting disulfide bond forming enzyme DsbB of Gram-negative bacteria

open access: yesNature Chemical Biology, 2015
In bacteria, disulfide bonds confer stability on many proteins exported to the cell envelope or beyond. These proteins include numerous bacterial virulence factors.

Review

open access: yes, 2020
The chalcogen elements oxygen, sulfur, and selenium are essential constituents of side chain functions of natural amino acids. Conversely, no structural and biological function has been discovered so far for the heavier and more metallic tellurium ...

The role of disulfide bond in hyperthermophilic endocellulase [PDF]

open access: yesExtremophiles, 2013
The hyperthermophilic endocellulase, EGPh (glycosyl hydrolase family 5) from Pyrococcus horikoshii possesses 4 cysteine residues forming 2 disulfide bonds, as identified by structural analysis. One of the disulfide bonds is located at the proximal region of the active site in EGPh, which exhibits a distinct pattern from that of the thermophilic ...

Determination of ADP/ATP translocase isoform ratios in malignancy and cellular senescence

open access: yesMolecular Oncology, EarlyView.
The individual functions of three isoforms exchanging ADP and ATP (ADP/ATP translocases; ANTs) on the mitochondrial membrane remain unclear. We developed a method for quantitatively differentiating highly similar human ANT1, ANT2, and ANT3 using parallel reaction monitoring. This method allowed us to assess changes in translocase levels during cellular

Structure and mechanisms of the DsbB–DsbA disulfide bond generation machine [PDF]

open access: yes, 2007
All organisms possess specific cellular machinery that introduces disulfide bonds into proteins newly synthesized and transported out of the cytosol. In E. coli, the membrane-integrated DsbB protein cooperates with ubiquinone to generate a disulfide bond,

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

open access: yesMolecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

Localization of Disulfide Bonds in Ribonuclease Using Low pH Trypsin and LC-ESI-QTOF-MS

open access: yesCHIMIA
We evaluated a method to localize disulfide bonds in bovine pancreatic ribonuclease (RNase) by applying low pH trypsin protein digestion with a bottom-up LC-ESI-QTOF-MS approach.

Cellular Disulfide Bond Formation in Bioactive Peptides and Proteins

open access: yesInternational Journal of Molecular Sciences, 2015
Bioactive peptides play important roles in metabolic regulation and modulation and many are used as therapeutics. These peptides often possess disulfide bonds, which are important for their structure, function and stability.
